Group Ski Club- On hill ideas

I don't want to toot my own horn but I'm the president of my colleges Ski and Snowboard Club. Obviously this club is my baby, so I've put in a lot of work to make it the best it can be.
We're coming up on our last trip of the year and I'm looking to do something with the whole group.
It's just a day trip where we bus up and bus back I'm a little restricted. I've tried to do Instagram contests where kids would win something if they found our banner off in the woods, we've gotten a decent amount of people together to run train, stuff like that.
I'm just throwing it out there, let me hear any creative ideas or suggestions.
